Question about flux

  1. May 27, 2014 #1
    I want to ask a question that does the electric flux passing through a hollow surface depends on the nature of the surface?That is does it depend on the relative permittivity of the surface εr??

    Please clear my confusion thanks .

    Yes it does.

    The electric field from the source will displace charges across the thickness of the surface. The displaced charges create an "induced electric field" across the thickness, which affects the electric flux through the surface.
